Due to the
richness and diversity of cetacean species that live in Chilean Patagonia-50% of the
species found in the worldand that particularly inhabit the area explored by
Atmosphere, we have created a complete observation program based on solid scientific
grounds.

This program includes amply trained guides and is committed to maintaining strict
sustainability guidelines. We have also added technology and comfort, features unknown to
the international whale-watching circuit, until now.

Watching Excursions
Whale-watching excursions last a full day or half-day and are held aboard the Zodiac
Hurricane 920 R.I.B. This watercraft has a 16-passenger, 3-crew member capacity and can be
safely used in a variety of marine conditions and settings.

Furthermore, Atmosphere also offers an observation platform located on the fifth deck,
with a wide visibility range.

Commonly Seen Species
Throughout Atmosphere`s navigation route there is a rich population of small endemic
cetaceans such as Peale`s dolphins, Commerson`s dolphins, Dusky dolphins and Chilean or
Black dolphins, together with a variety of considerably larger whale species: beaked
whales, rorquals, sperm whales, orcas - killer whales - and the always awe inspiring blue
whale, which in this region has a smaller fluke than its Northern hemisphere peers.

Scientific Approach
All approaching and operation techniques comply with the strict observation standards
suggested and required by such institutions as the Whale and Dolphin Conservation Society
and the International Fund for Animal Welfare, among others.

Furthermore, our guides will gather and record data which will contribute to scientific
research purposes.

One of these investigations that Nomads of the Seas® is collaborating with is the first
regional catalogue of recorded cetacean voices. Guests are welcome to help us record the
song of these gigantic creatures.

Blue Whale (Balaenoptera
Musculus)
33 meters max / More than 100 tons; Present in all the oceans of the world, and mainly
pelagic, the blue whale migrates to Antarctic waters in summer and returns to tropical and
subtropical waters in winter. This is the largest animal in the world. It has a long and
slender body, with a wide U-shaped head, and a small concave dorsal fin located on its
rear third. Its pectoral fins are long, thin and pointed, and have from 58 to 88 gular
folds. Its main feed is zooplankton which they eat in circumpolar zones, or else
cephalopoda, amphipoda, copepoda, and red crabs. Usually eats alone or with its mate,
separated by a long distance from each other, possibly due to the large space required by
their considerable sizes.

Fin Whale (Balaenoptera
Physalus)
25 meters aprox / 60 tons - Found in all of the Oceans, from the tropical zones to the
polar regions, fin whales are mainly a pelagic species and are believed to migrate to
polar waters in the summer to feed, and return to more temperate waters in the winter to
breed. this is the second largest animal after the blue whale, and grows to be as much as
22 meters long, with 50 to 100 gular folds on the abdomen. Fin whales are long and
slender, with a narrow V-shaped face, and a small sickle-shaped fin which they never
deploy when diving. Their air blast has the form of a long inverted cone, and their
pectoral fins are relatively fine and short. Fin whales are mainly characterized by their
asymmetrical pigmentation on the head, presenting some white whalebones on the right side,
and uniform grey whalebones on the left. Fin whales mainly feed on zooplankton, especially
krill, which they eat in circumpolar zones, in addition to small fish and squids.

Sei Whale (Balaenoptera
Borealis)
18 meters average / 20 tons - Preferably pelagic, may be observed in all of the oceans
throughout the world, especially in medium latitudes. While mainly recorded in tropical
and subtropical waters, Sei whales are believed to migrate to Antarctic waters. If we look
dorsally at the head, we may note that their mouth is less rounded than that of the blue
whale and less pointed than that of fin whales. Sei whales show a prominent crease in the
face from the nasal orifices to the tip of the mouth, and from 30 to 60 gular folds. The
dorsal fin is quite humped and is located much more to the front than other rorqual
species, while their pectoral and caudal fins are small. It feeds mainly on krill, but may
eat squid and fish of up to 30 cm. The feeding behaviour of Sei whales is a regular
swimming on the surface of the water with their mouths open, catching their feed.

Sperm Whale (Physeter
Macrocephalus)
18 meters max / 50 tons - Generally pelagic, but occasionally found in bays and canals,
the sperm whale is present in all the oceans of the world, from the Equator to the limits
of polar ice (60Â°N and 70Â°S). Young females and males are frequently found in
tropical and subtropical waters, between 40Â°N and 40Â°S, and adult males reach higher
latitudes during southern summers. Males may grow to be up to 18 m, while females are
quite smaller, up to 13 m, and may weight approximately 50 tons. Sperm whales have a
square head, which in males, is as much as 40% of their total body length. They dive down
to great depths in search for giant squids, their main prey. However, they equally feed on
octopuses, fish, crabs, and even small sharks and manta rays.

Southern Right Whale (Eubalaena
Australis)
17 meters max / Between 45 and 60 tons - In general, the southern right whale is found in
warmer waters during winter, and migrates to temperate regions in summer, and to sub-polar
regions to feed. This is a mainly coastal species, but there are oceanic records of it.
Very large in size, female southern right whales may be as long as 17 meters, males being
somewhat shorter. This species characterizes for having a round body, with no dorsal fin
or grooves below the mouth. Its head occupies almost 1/3 of the total body length, and its
arched mouth hosts long whalebones of up to 3 m. Near the nasal orifices and upper lip, it
has calluses or structures formed by natural skin thickening, where small crustaceans
live. These calluses allow for individual identification through photographic records.
During the southern summer, they swim in the cold waters surrounding the Antarctica,
feeding on small plankton organisms, such as krill, and copepoda which are abundantly
found there in that time of year. In general, they feed in the surface, and occasionally,
near the sea bottom.

Ballena de Bryde (Balaenoptera
edeni)
Up to 15 meters / Up to 20 tons - Brydes whales live in temperate and tropical waters in
the Pacific, Atlantic and Indic Oceans, generally between 30Â°N and 30Â°S.
Brydeâs whales have been recorded in coast and pelagic environments. This
species is mainly characterized by three prominent creases or "careens" which
are centrally or laterally projected from the nasal orifices to the mouth.
Brydes whales are able to make sharp turns of direction during feeding, mainly of fish and
certain low-depth crustaceans.

Humpback Whale (Megaptera
novaeangliae)
15 meters max / 40 tons - Mainly a coastal whale, but during migration and in the
Antarctic zone, it may be found in the pelagic media. Present in all the oceans of the
world, from the tropics where they reproduce, to polar seas, where they feed.
Nevertheless, there is evidence of whale populations which do not always migrate. Their
pectoral fins are very long and show protuberances, at least along the front edge. The
white or black pigmentation of the pectoral fins vary from one individual to another. The
humpback whale's body is wide, basically black or grey with a white abdomen and neck, and
a wide and rounded head showing flesh protuberances or warts and colonies of small
crustaceans (ciamida). Humpback whales feed mainly on krill and small fish banks.
Generally, they feed in the surface, no more than 50 meters deep.

Ballena Minke (Balaenoptera
acuorostrata)
Less than 11 mts / up to 9 meters approximately - Mainly pelagic, Minke whales may equally
be observed near the shore. They live in tropical, temperate and polar waters throughout
the world. In the Southern Hemisphere, during summer, they are observed south from 55 L s.
Characterized by their narrow slender trunk, with 50 to 70 gular folds which frequently do
not surpass pectoral fins. Minke whales have thin pectoral fins with pointed ends
underlined by a white strip, which is less frequent in the Southern Hemisphere. Their
whalebones are white-yellowish, but may have black pigmentation. Seemingly they feed in
cold waters, mainly on krill and small fish and crustaceans. In the feeding zones, large
congregations may be observed, apparently of up to 2,000 individuals.

Pygmy Right Whale (Caperea
marginata)
Less than 7 meters / 5 tons - There is scarce information on the pygmy right
whaleâs exact location, but several sightings and beaching episodes locate
this species in temperate and circumpolar waters of the southern hemisphere, north from
the Antarctic convergence. Coastal and pelagic, its distribution range has been estimated
from 31º S to 55º S. Its robust head is not too large and the mandibular exceeds the
maxillar arch that narrows its face. Unlike other right whales, its trunk is narrow and
slender; on its neck, two barely visible longitudinal folds are noted, with no calluses,
and a small dorsal curved fin, located so far back on the trunk that it remains invisible
when it surfaces. Females, larger than males, may be as long as 6.4 m and weight around
4.5 tons.
